China Breaks Ground on Key Rail Tunnels in Central Asia
Listen to the full version

China has broken ground on three tunnels that will form part of the China-Kyrgyzstan-Uzbekistan (CKU) railway, marking the project’s entry into major construction after nearly three decades of planning.
The start of construction by China Railway International Co. Ltd. in late April — two months ahead of schedule — was a milestone for a project first proposed in 1996. The CKU railway, once completed, will provide a shorter, more direct route connecting western China to Central Asia, bypassing Russia and enabling an overland alternative for trade with Europe.
